PUBLISHED DECEMBER 30, 1969 properties:

Molecular Weight About 1,000 to 5,000.

Melt viscosity, cp. (Brookfield) Less than about 2,500

' at 125 C.

Acid number About to 60.

Ring and ball softening point, C. About 95 to 140 C.

Density, C About 0.85 to 1.05.

when applied to fresh eggs, has been found to form protective coatings which greatly reduce the moisture loss by evaporation from the egg and retard spoilage of fresh eggs held at room temperature.

The preferred wax blends used in preparing the coatvings consists essentially of about to 100% by weight oxidized polyethylene and about 0 to 70% by weight paraifin wax. The wax blends are utilized for preparing emulsions consists essentially of about parts of the wax blendsfand about 14 parts surfactant, to about 150 parts water. The preferred surfactant is an emulsifier system of oleic acid and morpholine. The emulsions are then diluted with water to produce the coating material which contains a total of about 5 to 20% by weight of thewax blend and surfactant. Advantageously, about 90 to by weight of the coating material is blended with about 10 to 30% by weight of an alkali-soluble leveling agent.
